Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wastewater treatment methods are inefficient and costly, failing to permanently solve water pollution issues, as they rely on self-purification abilities of water bodies, require extensive land and time, or only temporarily clean water, limiting their application and effectiveness.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large ecological park is established to clean pollutants by water plants, then the purification capacity is improved, but the land area required increases significantly
Solution Approach 1:
The system divides the water purification process into multiple independent pools (sedimentation pool, anaerobic pool, anoxic pool, level-1 biological filter pool, and level-2 biological filter pool), each performing a specific treatment function. This segmentation allows the system to achieve comprehensive purification capacity while maintaining a compact footprint, as each pool is optimized for its specific function rather than requiring a large single-area ecological park.
Solution Approach 2:
The patent transitions from a horizontal land-area-based ecological park to a vertical multi-pool stacked configuration. By arranging purification pools in series and utilizing vertical space through multi-level structures, the system achieves high purification capacity without proportionally increasing land area, effectively moving the solution from two-dimensional land use to three-dimensional space utilization.
2Object-affected harmful factors
If the water bodies need self-purification ability, then the environmental impact is reduced, but the time required for recovery increases significantly
Solution Approach 1:
The system performs preliminary treatment actions by removing pollutants through multiple staged processes (sedimentation, anaerobic digestion, anoxic treatment, and biological filtration) before the water is discharged back into the water body. This preliminary removal of pollutants accelerates the recovery process and reduces the time needed for natural self-purification, while still maintaining environmental benefits by avoiding direct discharge of untreated wastewater.
Solution Approach 2:
The system implements continuous water circulation and treatment through the multiple pools, with water continuously flowing from one pool to the next and being continuously purified. This continuous treatment process maintains constant purification action rather than periodic intervention, significantly reducing the overall recovery time while preserving environmental benefits through sustained low-impact operation.
3Reliability
If mud cleaning and water re-injection is performed, then the water quality is temporarily improved, but the solution is not permanent and requires huge construction effort
Solution Approach 1:
The system employs self-service mechanisms where microorganisms and biological communities within the pools continuously degrade and remove pollutants from the water. The biological filtration pools contain microbial communities that naturally consume organic matter and convert nutrients, providing ongoing self-purification without requiring external intervention or complex mechanical systems. This biological self-service approach ensures permanent water quality improvement rather than temporary cleaning.
Solution Approach 2:
The system fundamentally changes the water quality parameters through multiple treatment stages, transforming polluted water into clean water by altering its chemical and biological composition. The sequential pools progressively change parameters such as dissolved oxygen content, organic matter concentration, nutrient levels, and microbial composition, achieving permanent quality improvement rather than temporary physical removal of mud. This parameter transformation approach creates sustainable water quality without huge construction efforts.
4Reliability
If multiple treatment pools are interconnected, then the purification effectiveness is improved, but the system complexity increases
Solution Approach 1:
The system segments the purification process into distinct functional pools, each handling a specific treatment task. This segmentation improves purification effectiveness by optimizing each pool for its specific function (sedimentation, anaerobic digestion, anoxic treatment, biological filtration) while managing complexity through clear functional separation. Each pool can be independently operated and maintained, reducing the operational complexity despite multiple interconnected units.
Solution Approach 2:
The interconnected pools serve multiple functions within a unified system framework. The same basic pool structure and operational principles apply across different stages, with each pool performing both treatment and habitat functions. This multi-functionality approach allows the system to achieve high purification effectiveness while managing complexity through standardized, repeatable modular units rather than entirely unique components for each pool.

AI summary
An ecological biowater purification system includes at least one water purification tank, each water purification tank including a water inlet, a water outlet, a water purification device, a suction device, a first backflow device and a second backflow device. In particular, the water purification device includes, in order, a sedimentation pool, an anaerobic pool, an anoxic pool, a level-1 and a level-2 biological filter pool, which communicate with one another via baffle boards and communication holes. Each suction device includes a plurality of suction nozzles and suction pipes for discharging precipitates out of the respective water purification tanks. The first backflow device is used to make some water in the level-2 biological filter pool flow back to the sedimentation pool, and the second backflow device is used to make some water in the level-1 and level-2 biological filter pools flow back to the anaerobic pool.
